Hi! I have several external regressors in my analysis that I configure with -taskreg in mkanalysis-sess (something like -notask -taskreg nameoffile 6). I was wondering how to set up mkcontrast-sess to contrast these regerssors given that I do not have a paradigm file for them. Can I just do something like -a 1 -c 2 -c 3 -c 4 -c 5?
Thanks, Caspar
Hi! A quick follow-up: I have a taskreg file with 6 continuous predictors. I would like to run specific contrasts, e.g., predictor 1 vs. mean(predictor 2:6).
From what I gather, selxavg3-sess will run automatic contrasts on taskregs,
but the automatic contrasts are against baseline. This is not what I need at this point. mk-contrast-sess does not like what I am putting in because I do not have a paradigm file in which condition numbers are specified. Is there a way to compute specific contrasts between multiple taskregs, and if not, is there a workaround? Thank you very much, Caspar

To get sig maps for an individual, this is problematic but I could probably come up with a work-around. For a group analysis, you can simply compute each taskreg separately, then subtract the two prior to running mri_glmfit. doug

Hi Doug, thanks for your reply. I would like to feed the differences into a FFX group analysis, so I think I will need to resort to your workaround. It would be great if you could provide that. Thanks! Caspar

Actually, you can still do each contrast individually. Each will produce ces and cesvar files. Take the difference between the ces files and the average of the cesvar files, then feed the result into mri_glmfit FFX

Actually, you can still do each contrast individually. Each will produce ces and cesvar files.

Hi Doug, just to clarify: If I want to contrast taskreg 1 vs. mean(taskreg 2,3,4,5,6), I would compute ces= ces(taskreg 1) - mean(ces(taskreg 2,3,4,5,6)) and cesvar=mean(cesvar(taskreg(1,2,3,4,5,6)))
Is that correct? Thanks, Caspar

Hi Doug, I am a little bit confused about the variance. Shouldn't the relevant variance be the variance over the differences, not the mean variance over all? Of course at the level of ces and cesvar, I do not have access to the timepoint by timepoint differences anymore. Is there another way to do this? Thanks, Caspar

Hi Doug, coming back to this once more. I am thinking that I can bypass mkcontrast-sess entirely if I provide a contrast matrix that has ContrastMtx_0 and WCond set to the contrast that I am interested in. For example [1 -0.2 -0.2 -0.2 -0.2 -0.2] to contrast my first continuous predictor and against the remaining five continuous predictors. For that, I would just place a corresponding mat file in a subdirectory in mystudy. Is there anything that speaks that and anything else that I need to consider? Thanks! Caspar

I don't know whether that will work or not. If it runs, you can compare the result to computing the contrast manually to see if there is a difference. If there is no difference, then it works.

Hi Doug, coming back to this once more. I am thinking that I can bypass mkcontrast-sess entirely if I provide a contrast matrix that has ContrastMtx_0 and WCond set to the contrast that I am interested in. For example [1 -0.2 -0.2 -0.2 -0.2 -0.2] to contrast my first continuous predictor and against the remaining five continuous predictors. For that, I would just place a corresponding mat file in a subdirectory in mystudy. Is there anything that speaks that and anything else that I need to consider? Thanks! Caspar

Hi Doug, I am a little bit confused about the variance. Shouldn't the relevant variance be the variance over the differences, not the mean variance over all? Of course at the level of ces and cesvar, I do not have access to the timepoint by timepoint differences anymore. Is there another way to do this?

Hi Doug, so I made contrast matrices and stored them in mystudy, and then ran selxavg3-sess per subject. I defined three different contrasts (in three mat files), but selxacg3-sess only gives me one analysis, it seems to be an F-test. When I do isxconcat-sess after that, I get six ces files per analysis (I presume one for each of my predictors), not three (number of contrasts).
Is there a way for me to force selxavg3-sess to actually compute the contrasts that I want?
Thanks, Caspar

I don't know whether that will work or not. If it runs, you can compare the result to computing the contrast manually to see if there is a difference. If there is no difference, then it works.

Hi Doug, coming back to this once more. I am thinking that I can bypass mkcontrast-sess entirely if I provide a contrast matrix that has ContrastMtx_0 and WCond set to the contrast that I am interested in. For example [1 -0.2 -0.2 -0.2 -0.2 -0.2] to contrast my first continuous predictor and against the remaining five continuous predictors. For that, I would just place a corresponding mat file in a subdirectory in mystudy. Is there anything that speaks that and anything else that I need to consider? Thanks! Caspar

Hi Doug, I am a little bit confused about the variance. Shouldn't the relevant variance be the variance over the differences, not the mean variance over all? Of course at the level of ces and cesvar, I do not have access to the timepoint by timepoint differences anymore. Is there another way to do this?

ok, so the issue is in fast_ldanaflac.m, around line 520: flac.con(nthcon).ContrastMtx_0=[]; that effectively ignores the contrasts that are set up in mystudy. caspar

Hi Doug, so I made contrast matrices and stored them in mystudy, and then ran selxavg3-sess per subject. I defined three different contrasts (in three mat files), but selxacg3-sess only gives me one analysis, it seems to be an F-test. When I do isxconcat-sess after that, I get six ces files per analysis (I presume one for each of my predictors), not three (number of contrasts).
Is there a way for me to force selxavg3-sess to actually compute the contrasts that I want?
Thanks, Caspar

I don't know whether that will work or not. If it runs, you can compare
the result to computing the contrast manually to see if there is a difference. If there is no difference, then it works.

Hi Doug, coming back to this once more. I am thinking that I can bypass mkcontrast-sess entirely if I provide a contrast matrix that has ContrastMtx_0 and WCond set to the contrast that I am interested in. For example [1 -0.2 -0.2 -0.2 -0.2 -0.2] to contrast my first continuous predictor and against the remaining five continuous predictors. For that, I would just place a corresponding mat file in a subdirectory in mystudy. Is there anything that speaks that and anything else that I need to consider? Thanks! Caspar

Hi Doug, I am a little bit confused about the variance. Shouldn't the relevant variance be the variance over the differences, not the mean variance over all? Of course at the level of ces and cesvar, I do not have access to the timepoint by timepoint differences anymore. Is there another way to do this?

That is what I thought. For version 6, I have a work-around which you might be able to use with version 5. Copy these files
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/fast_ldanaflac.m ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/flac_conmat.m
to $FREESURFER_HOME/fsfast/toolbox (make backups of the ones that are already there).
Then create a file for your contrast in the folder created by mkanalysis-sess (eg, yourcontrast.mtx). Note the mtx ending and not .mat ending. This is a text file with the contrast that you want. I would suggest making a contrast that replicates one of the other contrasts you made with mkcontrast-sess to assure that you have it right.

ok, so the issue is in fast_ldanaflac.m, around line 520: flac.con(nthcon).ContrastMtx_0=[]; that effectively ignores the contrasts that are set up in mystudy. caspar

Hi Doug, so I made contrast matrices and stored them in mystudy, and then ran selxavg3-sess per subject. I defined three different contrasts (in three mat files), but selxacg3-sess only gives me one analysis, it seems to be an F-test. When I do isxconcat-sess after that, I get six ces files per analysis (I presume one for each of my predictors), not three (number of contrasts). Is there a way for me to force selxavg3-sess to actually compute the contrasts that I want? Thanks, Caspar 2014-11-13 12:16 GMT-05:00 Douglas N Greve <greve@nmr.mgh.harvard.edu <mailto:greve@nmr.mgh.harvard.edu>>: I don't know whether that will work or not. If it runs, you can compare the result to computing the contrast manually to see if there is a difference. If there is no difference, then it works. On 11/13/2014 10:18 AM, Caspar M.
